App1ieation filed I anuary 25,

To all whom it may concern: V

. Be it known that I, ROBERT M. Nrcuors, a citizen of the United States,residing in the city and county of San Francisco and State .ofCalifornia, have invented a new and useful Improvement inBottleJVrapping Machines, ofwhi h the following is a specification.

The present invention relates to improvements in bottle wrappingmachines wheren a pair of arcuate drapers operate in conjunction withbottle feeding and paper,

Wra per feeding mechanisms to rotate the bott e and wrapthe paperwrapper thereon and also themeans for twisting one end of the wrapperaround the neck of' the First; to provide an improved bottle wrappingmachine;

Second, to provide-tan improved bottle wrapping machine adapted to wrapa cornparati-vely thin tissue paper wrapper around bottles;

Third, to provide improved, means for twisting a comparatively thinpaper wrapper around the neck of the bottle; Fourth, to provide improvedmeans-for folding the paper wrapper around and into the hollow bottomofthe bottle thereby effectively securing the wrapper to the bottlewithout the use of adhesives or-other sefcuring means; and Fifth, toprovide improved means for wrapping the exposed ends of the papersimilar parts wrapper closely to the bottle. I accomplish these "thepresent specification, \vhereinlike characters of reference are used 'todesignate throughout the said specification and drawings,'and in whichfFigure 1 is a broken vertical sectional view of them'achine disclosing,in dotted lines, the location of the bottle and paper wrapper;

Fig. 15 is a detailed view ofthe-driving, mechanism for the "ar cua'tedrapers.

Referring to the drawings the numeral l is used to designate a'suitablejhousmg or frame in the 1" werportion of which is rotatablymounted a drive shaft 2 having a suitable driving sheave 3 secured toone en thereof and a gear 4 meshing with a gear 6.

on a counter-shaft 7. The shaft 2 is also pro- 110.

I ions17 and 18 of the stationary and movable; arcuate drapers'19 and'20, respect1vely,.as

disclosed in Fig. of the drawings.

The drapers 19 and are composed of lower driving rollers 21 and 22Somewhat larger in diameter than the. pinions 17 and 18, the purpose ofwhich will-hereinafter be more fully described, and supporting roll edwithin suitable stationary bearings 26 ers 23 connected by means ofconnecting links 24. 'The drapers 19 and 20 are mounted upon thedriving. rollers 21 and 22 mountwhile the upper roller'23ofthestationary draper 19 is rotatably mountedwithin suitable bearings27 secured to the frame 1.

The movabled'raper 20 has its upper roller 23 rotatably mounted withinthe upper'ends of a pair of a'rms28-secured. to a countershaft 29 havinga pair of levers31 carrying a roller 32 to engage a cam 8 on thecounter- A bracket 36 carries a slideor base feeding device 37 downwhic'hbottle's 3e slide,

or roll by gravity. The feeding ofthe bottles, 38 into the extendeddraper 20, as disclosed in Fig. 3 of the drawings, is controlled by,

means .of a releasing cam.39 having a con- 'nection 41 to alever.42'having a roller 43-- arranged to be depressed by the lowering of Vthe arm 28 to operate the releasing cam 39 and thereby release onebottle only to the extended draper 20. p

A roll of wrappin paper 44 is rotatably mounted upon suita le brackets45 on the frame 1 and the web of paper passes over feeding rollers 46through upper guides '47, guide rollers 48 and stationary guides 49 andbetween the upper rollers 23 of both stationary and movable arcuatedrapers 19 and 20 which rotate the bottle 38 and thereby feed" said webbetween thesaid arcuate drapers' 19 and 20 and the bottle 38 therebywrapping the paper around the said bottle 38.

Both of the feed rollers 46 are slightly 'elastic in order to moreeffectively engage aed feed the web'of paper and either one of therollers 46 is provided with a cuttin knife 51 arrangedat anlangle' tothe axes o said rollers 46- whereby the ends of. each severed. sheet-ofpaper delivered to the areaate drapers Wlll lie at an angle'to the sidesv of the web and thereby wind or'wrap the.

oneeroller v loose end of the paper around the bottle in the form of ahelix thereby causing the paper wrapper to conform more closely to thebodyof the bottle 38.

The rollers 46 being slightly elastic and sli htly smaller than theothenitieevi ent the knife 51 will be slightly impressed into theopposite roller and at a different po nt on the periphery thereof ateachrotation so as not to disintegrate' said opposite roller/i6 aswould bethe case were-the knife 51 :to always out in the same'plaoe.

The rollers 46 are geared together by means of gears 52and are driven bymeans .of an upper s rocket 53 rigidly secured to one ofthe rol rs 46and'to a sprocket 54,

loosely mounted upon the cam shaft 11, b y means of a. chain 56. Thesprocket 54 1s provided with a clutch member 57 adapted 58 feathered'tothe counter shaft '11 and tuated by a cam 61 on the shaft 2.

to be engaged by a second clutch member 1 The shaft 2,is furtherprovided with a sprocket 63 having a chain connection 64 to a sprocket166 on a counter shaft 67 which is also provided with a gear' 68 meshingwith a gear 69 of a rotating'head 71 having I teeth 7 2 which mesh withpinions '73 secured to-yielding members 7 pivotally mounted bymeans ofthe arms 75 0ntoa'sleeve'7 6 secured to the frame 1 and'aroundwhichsleeve w the rotating head is rotatably mounted. v

A second sleeve 77 has s'lidably mounted thereonv a. cone 7&- actuatedby a lever 79in turn moved at the proper time by a cam 81 on the driveshaft 2 to move the said-cone :78 inward against the rollers 82 of thearms 83. The arms 83 operateagainst the extensions 84 of the yieldingmembers 7 4 to move said members onto the paper cylinder formed by thewrapping'of the paper web around the bottle 38 as disclosed in Fig. 5.of the drawings, and the continued rotation of; the bottle 38,'cause dby the'dra pers 19 and 20, together with the pressure of the yieldingmembers 74', twists the paper wrapper around the n ck of the bottle asdisclosed'in Fig. 6 o the drawings. 8

This leaves a small-projecting cylinder of paper wrapper extendingbeyond the head ofvthe bottle and this cylinder is laid or twisteddownonto the head of said bottle by means of the cup 86 attached to theendof a, rod 87 having upper and lowcr grooves 88 and 89 forothereception of opcrating" and'returning cables91 and 92."

. The operating cable 91 issecured to the 1 v outer end of the rod 87and after passing throughthelower groove 89 passes. over'a roller 93 andonto a drum 94 loosely mounted upon the counter shaft 67. The drum 94has a clutch member 95 adapted to be. engaged by a Similar clutchmember96 ac tuated by a lever 97 'which'isin turn operated by the face cam 98.1

The cup 86 is operated by the sleeve 77 which is in turn 0 rated by a,lever or arm 101 operating against the face cam 102 on the drive shaft2. i

anism disclosed in Figs;

The other end of the paper wrapper after being forined or wrapped aroundthe bottle 38 is turnedor folded into the hollow bottom of saidbottle 38by means of'the mech- 8 and 9 of the drawings, which consists of a pairof levers 103 pivotally mounted upon suitable brackets 10-1 secured tothe framel and connected by suitable connecting rods 106 to .a lever 107fulcrumedtothe frame 1 and having the lower end thereof operated by thefacecam, 108. on the cam 61 for operating the' paper feeding meehanism.

he levers are normally positioned as (Ills he" closed in Fig. 8 of thedrawings. c "m 108 will,- at the proper moment, move the levers 103 fromthe position shown in 8 to the position disclosed in Fig. 0 of thedrawings,.and fold the end 117 of the now cylinder paper wrapper-overand into a the hollow end of the bottle 38 as disclosed in Fig. 9 of thedrawings. In order to move the edge ofthe end 117 of the cylindricalwrapperdireetly toward the axis of the bottle 38, I have'provi'ded whatmay be termed an auxiliary lever 109 pivotally' mounted upon each lever.103 and normally held adjacent thereto by means of a T-shaped spring 111resting on the back of each lever 103 and having the T-end thereofresting upon the auxiliary levers 100' asdisclosed in'Figs.'8 and 9.

By means of this arrangement I have pro-' vided a leverpracticallyparallelto the edge of the paper. Wrapper to be turned or;folded agid as this paper is generally of the tissue per variety it mustbe delicately manipuated to prevent destruction. Vhen thelevels 103 and109 have moved through a right angle from the," position shown in Fig.vE5 of the drawings, the paper wrapperwil only lie at right angles tothe sidesorparal'lel 'to the bottom of the- .bottle 38 but in ordertofold the paper into the'hollow-bottom; thele ers 'inust remain in theposition shown whilc the levers V 103 move up into said hollow bottom.

This ispermitted' by'the are returning to normal position the slot 112engages the pin 113- in the end of each levcr10 l-and thereby returnssaid levers 109 ,tomormal position with a straigl'it edge lying parallelto the side of the-paper to he turned or the hollow bottom-of tl'ie lot-tle 38..

fA suitahledelivery' slide121 serves to deliver or conveyrthe' wrappedbottles from the machine. f

.. The operation is as follows:

The first step in the cycle is of the counter shaft 7 by means-ofthedrive shaft 2 and the gears pause the". arms 01' levers 'i'hovablearcuate diaper 20'to the end of the zwdiettlr feeding device or'clide3,7, j The arms .bottle 38 down the slide alining and supporting theT-shaped springs closed in Fig. 0

The rotation o f. the bottle 38 and the drapers 19 and 20'will engagethe end of the.-

paper wrapper and cause the same 'to be wrapped or wound around thebottle in a substantially cylindrical form as disclosed in dotted liliesin Fig. 1 of the drawings.

As soon as sulli'eient paper has been fed to the diapers- 1!) and 20 toproperlywrap thebottle' 38 the feeding mechanism, out: to the properlength and shape l nife-51 as hereinl'iefore described. The cam 81 nowoperates the which in turn urinates the. cone to-engage the extensionsof the rotating yielding members 74 and move said memhers 'against hrthe the end of the cylindrical paper wrapper bottle .38 as disiuljaeeptthe neck-of the.

38 by a forw aid movement of the cupu86 This extended cylindrical paperportion modification that may said forward movement being caused by theface 102 of the cam 81 which moves the lever 101 operating the sleeve 77which moves the cup 86 forward.

Meanwhile operates the lever 107 and causes-the connections 106 to movethe levers 103 and 109 to the position disclosed in Fig. 9 of thedrawings thereby folding'the opposite end 117 of the cylindrical paperwrapper over and into the hollow bottom of the bottle 38 thusefieetivelysecuring the wrapper to the said bottle.

The face 98 of the cam 81 next operates the lever 97 to move thefeathered clutch 96 into engagement with the clutch 95 of the drum 9%thereby winding the cable 91 onto said drum and moving the rod 87 andcup 86 against the head of the'bottle 38 thereby pushing the said bottlethrough the arcuate drapers 19 and 20, which have been meanwhileslightly released by the cam 8, and into the delivery slide121. Thedrive rollers 21 and 22 are of a larger diameter than the pinions 14and18 respectively, so that when the bottle 38 is moved longitudinallyfrom the machine, the saidlarger diameter oft-he rollers 21 and 22 willhold the bottle above the teeth of the pinions 17 and 18 to prevent saidteeth from tearing the paper wrapper on the bottle 38 as said bottle ismoved longitudinally into the delivery chute 121.

' The above operation is repeated for successive bottles.

It is obvious from the foregoing that'I have provided improved means for'wrapping bottles with delicate or flimsy paper wrappers in such amanner that the said wrappers will closely conform to said bottleswithout the use of adhesives or other securing means. l
